Bypassing charger Magnatek 6332

The camper we bought has a magnatek 6332 converter/charger. It had a battery in it that was 2 years old which has now been replaced because of bad cells. No biggie. But, I am not too sure on 30 year old tech for charging batteries and keeping them happy. I like to keep the camper plugged in when home so the fridge is cold and I can putter around.

That being said, I believe the magnatek will cook the battery again. I know I can buy a replacement panel for $200ish and I certainly will entertain that. I'm open to other ideas too.

But, in the meantime, while we are still fleshing this whole camper thing out, I'd like to simply not use the charger.

I figured, just remove the batter while at home, cover the positive lead and charge the battery using another charger in the garage. Then when we are ready to leave, plop the battery in and go. If I need to plug in while on the road, in short time frames, I assume it wouldn't fry the battery.

Good idea?
Bad idea?
Alternate idea?
  • I had one of those little battery boilers too, once upon a time.

    I’d replace the lower section with a PD4645V or PD4645VL from bestconverter.com. The L model supports lithium batteries.

    I keep mine plugged in all the time.

  • If you are worried about the charger, just buy a small charger for trips or break down and add a solar panel kit. If you think the charger/converter is possibly an issue, don’t risk it or you’ll be buying a battery depending on the warranty. Alternatively, plug in and test it out. If it kills your battery, go get a replacement.. If it doesn’t, you are good to go.

    Fwiw, I don’t think a bad charger will cause bad cells. More than likely, it would boil the liquid out and kill all of the battery. More than likely the bad cells are from vibration and separating the connection in the battery. Not a battery expert because mine don’t fail much, but I’ve never needed to replace a charger because of a battery with a bad cell on any vehicle/RV I’ve had.
